Intel wants manufacturers to only launch 700-series chipset motherboards with DDR5

Intel will launch this year’s 13th-generation Core series processors, also known as Raptor Lake, to replace the current Alder Lake. Both processors use the LGA 1700 socket and can support the same chipset, which means that Raptor Lake is also compatible with existing 600-series chipsets and should retain support for DDR4 memory.

According to TechPowerup, Intel will ramp up its push for DDR5 memory when it launches its 13th-generation Core series processors this year. Intel has asked motherboard makers to refrain from supporting DDR4 memory on the 700-series chipset motherboards to speed up the transition of its platforms to DDR5 memory. It is said that Raptor Lake will support DDR5-5600, which is a certain improvement over the existing Alder Lake’s DDR5-4800.

DDR4 and DDR5 motherboards have completely different UEFI codes in terms of memory support, and in order to ensure that Raptor Lake can run on 600 series motherboards, it will take some time for manufacturers to get the motherboards to work properly. Although Intel has requirements for motherboard manufacturers in this regard, according to past experience, individual brands may not fully comply. Intel most likely wants to end support for DDR4 after Raptor Lake. According to previous reports, there will be three 700 series chipsets, namely Z790, H770, and B760, while the low-end/entry-level market corresponding to H610 has not been updated. Compared to the 600-series chipsets, the changes to the 700-series chipsets are also relatively small.
